SPECIFICATION forming part of Letters Patent No. 305,080, dated September 167 1884.

Application tiled February 4, 1884.

To all whom, it may concern.-

Be it known that we, JAMES L. JUDD and HARRY WIARD, ofthe city of Syracuse, Onondaga county, ,State of New York, have invented certainnew and useful Improvements in Gultivators, of which the following is a description.

Our invention consists in a new and improved construction of certain parts of a cultivator, the frame of which we make of iron or steel bars, by which improvements we simplify and strengthen the implement and/give to the parts greater accuracy, simplicity, and facility of adjustmentthan cultivators heretofore made. XVe attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a top plan; Fig. 2, a side elevation; Fig. 3, the separate parts in detail.

Like parts in these figures are designated by the same reference-letters.

The frame of our cultivator consists of three metal bars, with their proper attachments. The center bar, a,- is straight from front to rear, its front end. a', being enlarged and of cylindrical form. (See Fig. 3.) Ahole through this forms an eye, through which the clevis-bolt passes. Cap-pieces b are fitted onto the bar above and below the eye a', having a rim around the edge, that forms an annular space between the eye and the cap s rim. Thisis seen at Fig. 3with thetop cap off at b. When these parts are together, the jaws of the clevis c (detached in Fig. 3) are slipped on over the caps b, which they embrace, and a single bolt is passed down through them, that holds them all together. rIhe clevis c is convex on its f front edge, extending upward, as shown in Fig. 2, with holes along its convex edge for the draft-clevis. Two arms, d, supporttthe cultivator-wheel. They are attached to this clevis by a bolt passing through them and one ofthe lower holes in the clevis, by shifting which the wheel can be raised or lowered. The rear ends of the bars d curve over, and are bolted to the center bar, a. To the rear end of bar c a tooth, e, is attached by a single bolt having a metal piece, e', interposed. This pieceis grooved on one side to t the bar, and on its other face there is a curved recess, into which (No model.)

l the curved shank of the tooth c fits, and the parts are united by a single square-shanked bolt through holes in them all. are bolted to the center bar, and the braces also, in the ordinary way. (ln Fig. 1 they are omitted.) The side bars, f, are curved at their front ends, to iit into the annular recess between the caps b and eye c". (See Fig-3.) Beyond this end curve the bar f is bent outward, and thence extends backward in astraight line to near the rear end, at which point it has a segmental curve, f outward. Beyond this the bar is'bent nearly at a right angle, and formed into a curved brace, f 2, bent on circular lines, centering at the joint, where they are united with the center bar, a, on the same plane. The two braces f2 lap one upon the other. Following the same curve, they pass through a clip, 7L, embracing the center har, at which point they are fastened by a setscrew through the clip, which holds the side bars, f, at any desired angle to the center bar, a. Teeth e are affixed to the side bars at any distance from the front end, and adjusted in pitch thereto by means of` a metal piece and bolt similar to that by which the tooth e is axed to the center bar, the curved shank and interposed piece permitting the pitch of the tooth to be changed without changing the elevation of the point or its distancefrom the bar f. A segment piece or block iits the concave side of the curve f in the barf, having a recessed seat for the rear tooth to fit, as with the other teeth, by which means the tooth can be adjusted horizontally by slipping the conveX piece around the segmental curve in the bar, and vertically by sliding the shank of the tooth up or down. Asinglebolt passesthrough holes in theseparts that are placed in line to be fastened.

Having thus fully described our improvements in the construction of cultivators, what we claim, and desire to secure by Letters Patent, is-

l. The combination of the center and side 95 bars, the caps b, clevis w, and central bolt, by which the center and side bars, caps, and clevis are all united, the parts being constructed and combined as and for the purposes specified.

The handles IOC 2. The side bars7 f, and braces f 2, formed in 3. The segmental curve f in the side bars,

in combination with the pieces e', having curved flanges for adjusting the teeth, in the 1o manner and for the purposes described.

4. The combination of the pieces e and curved shanks of the teeth7 for adjusting the pitch of the teeth Without raising or lowering their points, in the manner herein described.

5. In a cultivator having expanding side l bars and detachable clevis, as described, the cultivator Wheel connected therewith by means of the arms d, pivoted at their rear ends to the central bar in rear of the sde-barjoints, and adjusted by a bolt passing through a hole 2o in the clevis and the arms d, by which they can be raised or lowered, as and. for the purposes specified.

In witness whereof We have hereto set our hands.
